Warm lighting vs. Cool lighting: What is Better for Your Solar Street Lights?
Nov 15, 2024
As an efficient and environmentally friendly lighting device, solar street lights have been used in a variety of scenarios, such as highways, urban main roads, parks, residential communities, etc. In these different application scenarios, people consider different factors when choosing solar LED street lights, such as the height of the lamp pole, the capacity of the battery, the brightness of the light source, etc. There is another factor that must be considered, and that is the color temperature of the light, which is what we often call cool light and warm light. Next, let's analyze whether your solar street lights should choose cool light or warm light.
* Communities, parks, sidewalks: Solar powered outdoor street lights are installed in these areas where social activities are frequent to create a warm and comfortable atmosphere. Therefore, when choosing solar street lights, warm white light or natural light with a color temperature of 3000K-4000K is recommended.
* Commercial streets and landscape areas: Commercial solar powered street lights are installed in areas where commercial activities are frequent. They need to be both beautiful and practical. They need to blend with the surrounding environment and provide sufficient light. The recommended color temperature of solar street lights is 3000K-4500K.
* Special places (such as historical blocks or antique buildings): Such places should avoid overly bright lights that destroy the overall atmosphere and take into account the lighting effect. Choose solar street lights with low color temperature (<3000K) according to style requirements.
* Power and battery capacity: Low-power solar LED street lights usually choose low color temperatures to extend battery life; high-power lamps can support higher brightness and cool white light.
* Light efficiency requirements: If higher light efficiency is required, you can choose LED light sources with higher color temperatures.
* Natural light contrast: In areas with strong natural light during the day, cool white light is easy to blend at night, while low-color temperature solar powered LED street lights are recommended in areas sensitive to light pollution.
* Visual habits: The human eye is more sensitive to warm light at night and is more adapted to low color temperatures, while cool white light is easy to increase alertness.
* Customer needs: If it is a project based application, it is necessary to fully communicate with the customer to determine the best solution.
Color temperature range
1. Warm white light (2700K to 3000K)
Warm white light tends to be warm and light yellow, which can create a comfortable and relaxing atmosphere and is not easy to attract insects. Solar powered outdoor street lights that emit warm white light are more suitable for areas that require a comfortable and warm atmosphere, such as residential areas or park trails.2. Natural light (3500K-4500K)
Natural light in this color temperature range can provide good visibility and color rendering while maintaining a natural appearance. It is a balanced, neutral light that can be used in a variety of environments, especially commercial areas or parking lots. Commercial solar powered street lights require bright but non-glaring lights.3. Cool white light (5000K-6000K)
Cool white light is a bright blue-white light, which is very bright and has excellent visibility, but it is more glaring. Therefore, cool white light is more suitable for places with a particularly high safety index, such as construction sites and intersections. It is a very suitable light for safe lighting.How to choose solar street light color temperature?
1. Choose according to the application scenario of the solar LED street lights.
* Main roads and highways: When solar powered LED street lights are installed on main roads or highways, they are generally required to improve brightness and long-distance visibility, so cool white light with a color temperature of 5000K-6500K is recommended.* Communities, parks, sidewalks: Solar powered outdoor street lights are installed in these areas where social activities are frequent to create a warm and comfortable atmosphere. Therefore, when choosing solar street lights, warm white light or natural light with a color temperature of 3000K-4000K is recommended.
* Commercial streets and landscape areas: Commercial solar powered street lights are installed in areas where commercial activities are frequent. They need to be both beautiful and practical. They need to blend with the surrounding environment and provide sufficient light. The recommended color temperature of solar street lights is 3000K-4500K.
* Special places (such as historical blocks or antique buildings): Such places should avoid overly bright lights that destroy the overall atmosphere and take into account the lighting effect. Choose solar street lights with low color temperature (<3000K) according to style requirements.
2. Choose according to the component configuration of the commercial solar powered street lights.
* Check the light source specifications: The color temperature range of LED lamp beads is usually marked by the manufacturer (for example, 3000K, 4000K, 5000K, etc.).* Power and battery capacity: Low-power solar LED street lights usually choose low color temperatures to extend battery life; high-power lamps can support higher brightness and cool white light.
* Light efficiency requirements: If higher light efficiency is required, you can choose LED light sources with higher color temperatures.
3. Choose according to the environment in which solar street lights are used.
* Local climate: If there is a lot of haze or rain and snow in your area, the warm white light emitted by solar street lights has a longer wavelength and can provide higher penetration.* Natural light contrast: In areas with strong natural light during the day, cool white light is easy to blend at night, while low-color temperature solar powered LED street lights are recommended in areas sensitive to light pollution.
4. Choose according to visual comfort
* Glare control: If the road is narrow or there are many pedestrians, choose a solar powered outdoor street light with a lower color temperature to reduce glare and improve the comfort of walking at night.* Visual habits: The human eye is more sensitive to warm light at night and is more adapted to low color temperatures, while cool white light is easy to increase alertness.
5. Follow relevant standards or customer needs.
* Local regulations: Check the road lighting specifications of the installation area. Some areas have mandatory requirements for the color temperature of road lamps.* Customer needs: If it is a project based application, it is necessary to fully communicate with the customer to determine the best solution.
